List of TCP and UDP port numbers

From Wikipedia, the free encyclopedia

Jump to: navigation, search

This is a list of Internet socket port numbers used by protocols of the Transport Layer of the Internet Protocol Suitefor the establishment of host-to-host communications.

Originally, these port numbers were used by the Network Control Program (NCP) and two ports were needed as transmission was done at half duplex. As Transmission Control Protocol (TCP) and User Datagram Protocol (UDP) were adopted, only one port was needed. The even numbered ports were dropped. This is why some even numbers in the well-known port number range are unassigned. TCP and UDP port numbers are also used for the Stream Control Transmission Protocol (SCTP), and the Datagram Congestion Control Protocol (DCCP). SCTP and DCCP services usually use a port number that matches the service of the corresponding TCP or UDP implementation if they exist. The Internet Assigned Numbers Authority (IANA) is responsible for maintaining the official assignments of port numbers for specific uses.[1] However, many unofficial uses of both well-known and registered port numbers occur in practice.

Well-known ports

The port numbers in the range from 0 to 1023 are the well-known ports. They are used by system processes that provide widely used types of network services. On Unix-like operating systems, a process must execute withsuperuser privileges to be able to bind a network socket to an IP address using one of the well-known ports.
